TIRE.

945,037. Specification of Application filed July 18,

To all whom it may concern:

Be it known that I, DAVID HAYS, a citizen of the United States, and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Tires, of which the following isa specification.

My present invention relates to improvements in tires and moreparticularly to means for readily attaching and detaching theclencher-shoe in connection with the rim.

The advantages of the invention will appear from an understanding of.the following description and drawings.

In the drawings which show only one of the forms which my improvementsmay take, Figure l is a crossssection partly in elevation of a folly andtire, showing my device in combination therewith; Fig. 2 is a viewpartly in vertical section and partly in elevation of said devicedetached and shown on an enlarged scale from that in Fi 1, with. itsparts also shown in different positions of adjustment; Fig. 3 is a planview looking on-top of the devices in Fig. 2 with band l t elevated;and, Fig. 4 is a View of a detail.

Describing now my invention with particular reference to the devices ofthe drawings and reserving it to the claims to point out the novelfeatures, Fig. 1 shows the section of a felly 1 carrying a band 9.flanged only. at one side 3 to permit the removal and insertion of therim 4- into surrounding position over the band from its non-flanged oropen side. To secure therim in position on the band, clamping devices ofany well known form can be provided suitably spaced about the wheel, ofwhich one is indicated at 5 in Fig. 1. The connecting means between saidclamping device and the band or felly. may be of any well known sort andis not indicated in the drawing.

The sides of the rim 4 may be upturned, as usual to act as seats for theelenchcr flanges 6 of the shoe 7.

The means for spreading apart the clencher-flanges against the sides oftherim and at the same time for securing the tire and rim rigidly to thefelly comprises in 1 part the well known device, conveniently called aspreader, which may consist of a plate 8 of more or less wedge ortrough-like contour resting inside the clencher-shoe be I tween and 111contact with its s1des,sa1d plate I IlettersPatent- Patented J an. 4,1910. 1908. Serial No. 444,289.

supporting a depending screw-threaded stem 9 which passes through anopening in the rim. Of these Spreaders there are a plurality spacedabout the wheel. Moreover the usual arrangement comprises nuts on thestems 9 next the inside of the rim, whereby taking up on said nuts drawsthe stems and consequently theplates 8 toward the rim with resultantforcing apart of the clencher flanges 6 against the sides of the rim.

My present improvements do away with the nuts on the threaded stems andsubstitute devices similar to that shown in Fig. 2. Said devicescomprise in the particular form shown an externally threaded sleeve 10having spring arms 11 extending longitudinally therefrom, said arms attheir ends being internally screw-threaded at 12 to engage, whentogether, the threads on the stem 9. The spring arms 11 normally occupythe expanded position indicated in Fig. 2 in which their screw-threadswill not engage the threads on the stem 9. A band ll is providedslidable along and inclosing the arms 11, whereby when the band is slidinto a position toward or over the threaded portions .of the arms, saidportions will be brought together into engaging position relative to thethreads on the stem 9. The means for thus operating the band 14 maycomprise a rod 15 movable-axially within the sleeve 10,

said rod having radiating fingers 16 which come out through spacesbetween the arms and are attached to the band 14. The rod may beprovided. with a head 17, which for convenience in assembling thedevices in Fig. 2 may screw-connect with said rod somewhat as indicatedin Fig. 4.

A washer .18 is provided loosely surround ing the sleeve, also a wingnut19 engaging the threads on said sleeve for a purpose hereinafterdescribed.

The device is used as follows, the described manipulation being repeatedin connection with each of the similar devices, of which it will beundcrstood there are a plurality, spaced about the wheel. Thusregistering with the openings in the rim for the threaded stems 9 areopenings 20 through the band and fellv, said openings being suitablylarge to permit the ends of the arms 11, when in the expanded positionshown in Fig. 2. to be passed up through said openings into Suiroundingposition about the particular threaded stem 9, whereupon the rod 15governing the sliding band l l is pushed inwardly to compress the armsand bring their threaded portions into engagement with the threaded stem9, thereby securely uniting my attachment to said stem. This beingaccomplished, the wing nut 19 is operated to force the Washer againstthe felly and then to draw my device and along with it the interlockedspreader toward the felly with the combined result, first of spreadingthe clencher flanges inseparably into the sides of the rim, andsecondly, of rigidly securing the tire and rim to the folly.

The great advantage in among other respects of the aforesaid devicecomes in when assembling or making repairs, as for example in replacinga shoe or inner tube or both, especially when on the road. Such acontingency, with the old style nut secured stems 9, necessitated aremoval of all the clamps 5', since the rim must be taken off the wheelin order to get at and remove the nuts. These same steps had to beduplicated in reverse order, in replacing the tire and rim and thereforethe operation was both a lengthy and troublesome one, much simplified bymy improvement. as follows. Thus to replace a tire it is not necessaryat all to remove the clamps 5 to get at the rim, on the contrary theseparts are all left intact. The

only manipulation required is to loosen the wing-nuts 19 -sufficientlyto permit the spreaders to be pushed back into the tire to release thecleneher flanges and allow their withdrawal from the rim. Similarlyafter the shoe is replaced, it is only necessary to' take up onwing-nuts 19 to draw the spreaders toward the telly to wedge theclencher flanges securely within the rim. Thus it will be noted thatneither operation requires the manipulation of the rods 15 to releasethe gripping jaws from the Spreaders; much less do they require theremoval of the clamps 5 or of the rim 4. However should for any reasonit be desired to remove both the tire and rim from the telly, it is onlynecessary in addition to pull out the rods 15 to release the grippingjaws from the spreaders, whereupon the tire and rinr can be slid off thefelly, the clamps 5 having been also removed.

Having thus described my invention, what I claim is:

1. A device adapted to be used in connection with a clencher-shoespreader and a felly, comprising in combination a sleeve having armsprojeetingfrom one end insertible through an opening in the folly, saidarms being adapted to grip the spreader when brought together, a bandinclosing said arms and slidable thereon, a rod working in the sleeveand having operative connection with the band, and means adjustable onthe sleeve for delivering thrust against the folly to draw the spreader,gripped by the arms, toward the felly.

2. A device adapted to be used in connection with a cleneher-shoespreader and a felly comprising in combination an externally threadedsleeve having spring arms projecting from one end of the sleeveinsertible through an opening in the felly, and adapted to grip thespreader when the arms are brought together, a band inclosing said armsand slidable toward their extremities to bring said arms together intogripping position. a rod working in the sleeve having integralconnection with the band by fingers which extend between the springarms, and a nut engaging the threads on the sleeve and adjustable toexert thrust against the felly.

In witness whereof, I have signed my name to the foregoing specificationin the presence of two subscribing witnesses.

DAVID HAYS.
